It would actually be kind of a cool feature for the career mode if they made it right.
Pay for the tires you use (a set between 400-2000Cr depending on car) instead of paying 6000 for "Sport" once.
(6000 is to much for one set, not enough for "lifetime refill".
Pay for the fuel, brake pads/discs, shocks...
But you can only do that for road cars, every one knows that it is impossible to run a race car/team on price money only.
And you have to get the deterioration rates right...
300 miles is a joke, even the tires should last that long...
Tires should last much longer than 300 miles, especially on racers.
Here are my easy calculations anyone can do for the r18 on racing mediums at La based off of the 2011 model)
If a track is 8.47 miles long, and an R18 averages a lap time of 3'24", and one set of tires lasts up to five stints (12 laps), find the total amount of miles one set of tires can do until a new pit stop.
Track: 8.47
Lap time: 3:24
Tire longevity: 5 stints
Time to complete one stint: (12x3.24=38.88)
8.470000000000001 : 3.24 = 2.61419753086 miles/min
2.614197530864199 × 38.88 = 101.64 (miles/min) x (min/1) = miles/stint
101.6400000000001 × 5 = 508.2 miles for 5 stints
In Gt5, I could barely get ten laps out of RM's with my 908 at whatever regs it ran in '10. It's total mileage for an average lap time of 3:30 is as follows..
Time to complete one stint: 10 × 3.3 = 33 min
8.470000000000001 : 3.3 = 2.56666666667 miles/min
2.566666666666667 × 33 = 84.7 (miles/min) x (min/1) = miles/stint
So basically here are the side-by-sides
Miles for a set of tires in reality: 508.2 (for 5 stints at 3.24 avg lap time)
Miles for a set of tires in GT5: 84.7 (for 1 stint (because I can't get anything else out of them after 10 laps) at 3.3 avg lap)
Now, it should be also noted that the range for the R18 (on diesel) can do about 11 laps before bingo fuel. I'm not sure what it is on GT 6 as I haven't gotten the time to get enough credits, but if someone here can vouch for the amount of laps before it goes to reserves and what location around Le Mans (by description, picture, or location on track) that would be great. I am also unsure if you can choose to only get fuel. For my this should be implemented as such if I need a quick splash I can jump in and stay in the lead for a while to come back in latter. I have no idea why they can't just put a zero option for all 4 tires (which also means that I should be allowed to specifically choose which tire on which wheel on which axel).
It is absurd just looking at those numbers and think that this is a sim... I'm not a great driver when compared to Tom, Allan, or Andre, but I should be able to do more than 1 stint on a freaking set of tires...
